## Public constructors

### TilePreviewData

Added in [1.4.0](https://developer.android.com/jetpack/androidx/releases/wear-tiles#1.4.0)

```
public TilePreviewData(
    @NonNull Function1<@NonNull RequestBuilders.ResourcesRequest, @NonNull ResourceBuilders.Resources> onTileResourceRequest,
    PlatformDataValues platformDataValues,
    @NonNull Function1<@NonNull RequestBuilders.TileRequest, @NonNull TileBuilders.Tile> onTileRequest
)
```

| Parameters |
|---|---|
| `@https://developer.android.com/reference/androidx/annotation/NonNull Function1<@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/wear/tiles/RequestBuilders.ResourcesRequest, @https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/wear/protolayout/ResourceBuilders.Resources> onTileResourceRequest` | an optional callback that provides a `https://developer.android.com/reference/androidx/wear/protolayout/ResourceBuilders.Resources`. If the layout provided in `https://developer.android.com/reference/androidx/wear/tiles/tooling/preview/TilePreviewData#onTileRequest()` uses automatic resource registration (either from `https://developer.android.com/reference/androidx/wear/protolayout/material3/package-summary#materialScopeWithResources(android.content.Context,androidx.wear.protolayout.ProtoLayoutScope,androidx.wear.protolayout.DeviceParametersBuilders.DeviceParameters,kotlin.Boolean,androidx.wear.protolayout.material3.ColorScheme,kotlin.Function1)` or other methods from `https://developer.android.com/reference/androidx/wear/protolayout/ProtoLayoutScope`), this callback will not be needed and, if provided, will be ignored. In other cases, it will be called before rendering the preview of the `https://developer.android.com/reference/androidx/wear/tiles/TileBuilders.Tile`. By default, this callback will return resources automatically collected from the rendered tile via `https://developer.android.com/reference/androidx/wear/protolayout/ProtoLayoutScope` if they exist, or `https://developer.android.com/reference/androidx/wear/protolayout/ResourceBuilders.Resources` with the version "0" otherwise. |
| `https://developer.android.com/reference/androidx/wear/protolayout/expression/PlatformDataValues platformDataValues` | allows overriding platform data values for any `https://developer.android.com/reference/androidx/wear/protolayout/expression/PlatformDataKey`. Default platform data values will be set for all platform health sources that have not been overridden. |
| `@https://developer.android.com/reference/androidx/annotation/NonNull Function1<@https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/wear/tiles/RequestBuilders.TileRequest, @https://developer.android.com/reference/androidx/annotation/NonNull https://developer.android.com/reference/androidx/wear/tiles/TileBuilders.Tile> onTileRequest` | callback that provides the `https://developer.android.com/reference/androidx/wear/tiles/TileBuilders.Tile` to be previewed. It will be called before rendering the preview. |

### getPlatformDataValues

Added in [1.4.0](https://developer.android.com/jetpack/androidx/releases/wear-tiles#1.4.0)

```
public final PlatformDataValues getPlatformDataValues()
```

allows overriding platform data values for any `https://developer.android.com/reference/androidx/wear/protolayout/expression/PlatformDataKey`. Default platform data values will be set for all platform health sources that have not been overridden.
